Ignore Blank Values and Inactive Records in Duplicate Detection

This has been an issue, but with CRM roll up 5 this has been rectified.

If you want to do this and it’s not in your CRM 2011 then please check the roll up version. Only with CRM roll up version 5 this comes. However this roll up cannot be uninstalled.
